IMPROVEMENT IN REFRIGERATING SHIPPING-BOXES.

Specification forming part of Letters Patent No. 188,609, dated March 20, 1877 5 application filed September 9, 1876.

To all whom it may concern: 4

Be it known that I, HENRY A. DUO, J r., of Charleston, in thecounty of Charleston and State of South Carolina, have invented certain new and useful Improvements in Refrigerating Shipping-Boxes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to refrigerating shippin g-boxes, for the transportation of fruit, vege etables, 8tc.; and it consists in providing a suitable case with one or more series of alternate closed removable ice-boxes and openremovable fruit-boxes, all being of the same size, so as to be interchangeable, one for another, as will be hereinafter more fully set forth. Q

In order to enable others skilled in the art to which my invention appertains to make and use'the same, I will now proceed to describe its construction and operation, refer ring to the annexed drawing, in which- Figure 1 is a perspective view of my invention with the cover of the outside box or case removed. Figs. 2 and 3 are perspective views, respectively, of the fruit and ice boxes.

' A represents the outer or shipping box or case, constructed, in any" suitable manner, with double walls, having the space between them filled with some suitablenon-conducting B is the cover of the case A, constructed in similar manner. 0 O represent closed boxes of any suitable material, provided with screw caps or covers G, to renderthesame perfectly tight. These boxes are intended to hold ice, or any suitable refrigerating mixture, and the caps or covers Gr prevent any leakage, so that the refrigerating material,

whatever the same may he, cannot escape and i come in contact with the fruit, to spoil the same in any Way. D D represent ordinary open or slat fruit-boxes, made of any suitable materia]. The ice-boxes O and fruit-boxes D are of precisely the same size and shape. and are arranged alternately in the box or case A.

In shipping fruit, &c., it depends upon the season of the year, as well as the distance the articles have to go, whether more or less refrigerating material! is needed. If the iceboxes were stationary in the outer case the same space would be occupied, whether much or little ice were needed, and only the same quantity of fruit could be shipped in each case.

By my invention of having removable ice and fruit boxes of the same size, and interchangeable, oneforanother, itis readily seen that more or lossice can be used, as required, and that no more room is taken up for ice than just what the ice occupies, and the whole remaining space may be tilled with fruit-boxes; and the ice-boxes may be distributed among the fruit-boxes in any manner desired to accomplish the best result.

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

A refrigerating shipping-box, consisting of an exterior case, A, with cover B, and containing a number of closed ice-boxes, (J, and open fruit-boxes l), which are removable and interchangeable, one with another, substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signature lll presence of two witnesses.
